“…In addition, Lou et al [ 61 ] reported the high-temperature deformation performance of AC-10 and SMA-10 blended with different contents and lengths of BFs. The data showed that for AC-10, when 3 mm BFs with 0.2%, 0.3%, 0.4%, and 0.5% content were added, the dynamic stability of the ultra-thin abrasion layer was improved by 99.3%, 69.7%, 31.0%, and 21.8%, respectively, while the rutting depth percentages were reduced by 31.7%, 23.0%, 18.3%, and 8.9%, respectively, compared with pure asphalt.…”

“…Lou et al [ 61 ] further investigated the effect of mix grading and fiber length on low-temperature properties by low-temperature bending beam tests. For AC-10, the maximum breaking strain and the minimum bending stiffness modulus were found when 0.2% of 3 mm BFs were added.…”

“…BFs formed a spatial networking structure in the asphalt mixture, acting as reinforcement and toughening. Lou et al [ 61 ] for the effect of fiber admixture and length concluded that for AC-10, the residual Marshall stability values were greatest when the 3 mm BF content was 0.2% or when the 6 mm BF content was 0.3%. In SMA-10, the water stability index is higher than other mixes with the addition of 0.3% BF (3 mm or 6 mm).…”

“…In terms of rutting resistance, the addition of BFs is beneficial. Lou et al [ 61 ] conducted the sand patch test and pendulum test and found that the influence of BF length on slip resistance was not significant. Tanzadeh et al [ 47 ] found that the addition of fibers made the OGFC more abrasive and raised the oxidation sensitivity of the asphalt mixture, and that adding nano-silica was able to reduce the degree of improving the negative impact to some extent.…”

This paper conducts a thorough review of the literature on the feasibility and current state-of-the-art incorporation of basalt fiber (BF) into asphalt pavement materials, focusing on fiber characteristics, dosage, incorporation methods, mixture properties, and surface modification techniques. The optimum basalt fiber dosage should be determined based on engineering performance parameters such as asphalt type, fatigue cracking, thermal cracking, rutting, and moisture resistance of asphalt mixtures. Basalt fibers are added to asphalt mixes by dry method or mixed method to achieve better dispersion. Adding BF to asphalt mixtures increased performance characteristics like cracking resistance, rutting resistance, and fatigue resistance. Overall, incorporating BF into asphalt mixtures would lower costs while increasing pavement service life. More research is needed to fully understand the effects of different sizes of BF on pavement performance and the possible environmental and economic repercussions of fiber surface alteration.

“…Skeleton pattern gradation helped improve the high-temperature rutting resistance and anti-skid performance [3,21]. Researchers also added basalt fiber to improve the crack resistance and raveling resistance of UTWC [22]. In addition, SMA-10, Novachip-B, and GT-10 gradation were widely used in UTWC and found to have excellent comprehensive performance [15,16,18,23,24].…”

Ultra-thin wearing course (UTWC) as an asphalt overlay is widely used in pavement maintenance for extending pavement service life. Researchers focused on improving and evaluating its performance, yet few researchers compare the performance of typical UTWCs. Moreover, some traditional asphalt mixture tests are improper for UTWC due to the thicknesses of UTWC, which is thinner than the traditional asphalt overlay. This study further evaluated the advantages and disadvantages of typical UTWCs. A series of tests were conducted to compare the comprehensive performance of three typical UWTC products, including SMA-10, Novachip-B, and GT-10. Moreover, this study improved the rutting test to evaluate its rutting performance more accurately. Rutting specimens of 20 mm thick and 50 mm thick composite specimens (20 mm UTWC + 30 mm Portland cement concrete slabs) were prepared. Two types of PCC slabs were used, including unprocessed PCC slabs and PCC slabs with preset cracks. The test results showed that Novachip-B showed the best water stability and weakest raveling resistance, while GT-10 showed the best fatigue and anti-skid performance. The rutting performance of UTWCs was reduced because of the influence of preset cracks. The rutting depth of GT-10 was only 60–90% of that of others, showing the comprehensive performance of GT-10 was better than that of others. These results provide a significant reference for the research and application of UTWC.
